AUTOMATIC STOP ATTACHIIEN T FOR PHONOGRAPHS.

Specifipation of Letters Patent.

Application filed August 17, 1907.

Patented Nov. 24, 1908.

Serial No. 389,067.

To all whom it may concern:

Be it known that I, EDGAR'B. HYATT, a citizen of the United States, and a resident of the city of Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Automatic Stop Attachments for Phonographs, of which the following is a specification, reference being had to the accompanying drawings as constituting a part thereof. v

This inventionhas for its object to provide simple means whereby the motor mechanism of a phonograph may be automatically stopped at the end of the selection being To this end my improvement essentially consists of a braking element arranged to engage with one end of the cylinder, and automatically thrown into action by contact devices carried by the carriage, arranged to act at the end of the selection being rendered. My stopping devices being furthermore so designed that they can be readily applied to any standard phonograph of the type in mind.

The details of the construction and mode of operation of my attachment are readily understood from an inspection of the drawings, in which,

Figure 1 shows a perspective detail of a phonograph with my attachment applied thereto as in practice; and Figs. 2 and 3 are details of construction of my attachment.

The letters designate the parts described.

The parts of the phonograph not specifically described are understood to be of the usual standard make' 7 On the bed-plate a is journaled the usual record-cylinder 72, the shaft of which has an extension 0, made with an exterior thread and constituting the usual feed-shaft; the feed-shaft and therewith the cylinder, being rotated by the usual motor-mechanism of this class of phonographs which it is not necessary to illustrate. Arranged parallel to the feed-shaft c is a rigid shaft (Z, on which pivots and travels the carriage 6. Such carriage being provided with an integral arm 6 having on its extremity a diaphragm-head, which parts are supposed to be broken away from the sectional detail in Fig. 1. Part of the carriage 'e, as will be noted, is also broken away to avoid obscuring the attaching means of my device.

On the rigid shaft 03 is rigidly mounted an arm f, a detail of which is shown in Fig.

The same is provided with an eye/i, through which to insert the shaft (1, it is made goose-neck shaped, is provided with a flat surface (I, and an upwardly projecting shoulder or stop-lug y. A perforation is provided at /a through which to insert a setscrew Z, by which is rigidly secured to the arm 1' a laterally projecting arm m, and at a is provided a perforation through which tq insert a rivet 0 whereby to pivotally secure a brake-lever 0, the outer end of which arm is connected with the extremity of the arm mby a coil-spring 1).

However, I do not confine myself to the details described; for example, the arm. m could be made an integral part of the arm f if deemed more convenientfi q is the usual arm rigidly projecting from the carriage e and having at its extremity a nut engaging with the feed-shaftc. On the arm 9 is rigidly secured, .by means of an angle-plate g, or otherwise, as is convenient, a plate '2', having an inclined upper edge 1-. The extremity 0 of the lever 0 istapered to facilitate its climbing "up on the inclined.

edge 1". On the inner end of the lever 0 is provided abox a, in which is secured a disk of friction material t, the whole constituting a brake-shoe. It will be noted that all of the parts of my attachment may be readily aflixed to the standard make of phonographs of the ty e illustrated.

The operation 0 my device is as follows: Normally the lever 0 will impinge upon and be held by the stop-lug j, thereby holding the brake-shoe 16 clear of the head b of the cylinder b, and allowing the latter to be revolved by the motor-mechanism. Sup osing the carriage e to be at the starting p ace of the phonograph, and to be traveling to the plied with a new record, the act of moving the 'carriage, by means-of the usual arm 6 (carrying at its end the diaphragm-head) back to the starting place, will bring said arm 6" against the lever 0, and return the same to its position in front of the stop-lug,

j; the lever 0 being caused to drop into place, in front of said stop-lug j,.by,-reason of the far end of the coil-spring p being attached to the arm m, which is in a lower'plane, and therefore causes such coil-spring pto exert a down pull. j

I claim:

1. A phonograph stopping attachment comprising in combination with the recordsaid piece on the carriage by the act of returning the latter to its starting position.

2. A phonograph stopping attachment comprising in combination with the recordcylinder, a carriage and supports therefor, 11 projecting piece on the carriage, a support ing-bracket, a brake consisting of a lever pivoted on said bracket, extending horizontally transversely of the record-cylinder and the carriage, and a brake-shoe on said lever arranged to bear upon the end of the recordcylinder, a coil-springarranged to operate. .the brake-lever to apply the brake-shoe, a stop to hold the brake-lever in inactive position, and a contact device, carried by the carriage, arranged to engage with the outer end of the brake-lever and disengage the same from the stop and allow the brake to be applied atthe end of the selection bein rendered; said holding means for the bra e being arranged to be thrown into action .by contact therewith of said piece on the carriage by the act of returning the latter to its starting position.

3. A phonograph stopping attachment comprising in combination with the record-cylinder, a carriage and supports therefor, a projecting arm on said carriage, a supporting-bracket having a horizontal fiat bearingsurface and a vertical stop-lug thereon, a brake-lever pivoted on the bearing-surface of the bracket, extending transversely of therecord-cylinder and the carriage, and provided with a brake-shoe arranged to bear on the end of the record-cylinder, a coil-spring arranged to operate the brake-lever to apply l theLbrake-shoe, one end of said coil-spring being attached below the plane of the bear-' ing-surface'of the bracket for the purpose .on theparriage and arranged to enga e with same clear .of the stop-lug and allow the brake tobe applied at the end of the selection being rendered, and the parts being arranged to cause the projectingarm of the carriageto-engage with theouter end of the brake-lever to return the same in front of .said stop-lug by the act of returning the carriage to its starting, position,

4:: A phonograph stopping attachment projecting arm on said carriage, a supportin'g-bracket having a horizontal flat bearingbrake-lever pivoted on the bearing-surface of the bracket, extending transverselyoi' the end thereof made tapering andthe inner end on the end of the record-cylinder, a coilspring arranged to operate the'brake-lever to apply the brake-shoe, one end of said coil spring being attached below the plane of the bearing-surface of the bracket for the purried on the carriage arid arranged to engage with the outer tapering, end of said brakelever tolift the same clear of the stop-lug and allow the brake to be applied at the, end of the selection being rendered, and the parts of said stop-lug by the act of returning the carriage to its starting position. i

. In a talking machine the combination with a mandrel and the diaphragm carrying element, of a brake pivotally supported at the machine-by engaging both' the diaphragm carrying element and the mandrel.

6. In a talking machine the combination with a mandrel and the diaphragm carrying element, of a' brake pivotally supported at the end of the mandrel and adapted to be actuated b the diaphragm carrying element to engagea d stop the mandrel.
